Which company owns MAC address prefix B8:A8:AF?

MAC address prefix B8:A8:AF is registered to Logic S.p.A. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B8:A8:AF has a network interface built by Logic S.p.A..

What is the OUI B8:A8:AF?

B8:A8:AF is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Logic S.p.A.. It covers every address from B8:A8:AF:00:00:00 to B8:A8:AF:FF:FF:FF, or 16,777,216 addresses in total. It is also written B8-A8-AF.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B8:A8:AF:00:00:00 that is B8:A8:AF — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is Logic S.p.A. located?

Logic S.p.A. is listed at Via Galilei 5 Cassina de' Pecchi MI IT 20060 in the IEEE OUI registry entry for B8:A8:AF. This is the address the organization registered with the IEEE, which may differ from its current operating address.

Logic S.p.A.

MAC address prefix B8:A8:AF is registered to Logic S.p.A. in the IEEE OUI registry. Any device whose MAC address begins with B8:A8:AF has a network interface built by Logic S.p.A.. This prefix (the OUI, or Organizationally Unique Identifier) is assigned by the IEEE and is the first three octets of the address — it covers every MAC from B8:A8:AF:00:00:00 to B8:A8:AF:FF:FF:FF.
